To ensure the proper function of the air mass meter -G70- it is important to adhere to the following work sequences.
  Note
t  If the air filter element is very dirty or wet, particles of dirt or water may reach the air mass meter and falsify the measured air mass value. This would lead to loss of power, since a smaller injection quantity is calculated.
t  Always use a genuine spare part air filter element.
t  Always renew seal if damaged (air leaks in intake system).
t  Use a silicone-free lubricant when installing the air hose and seal.
t  Hose connections and air pipes and hoses must be free of oil and grease before assembly.
t  Secure all hose connections with the hose clips corresponding to original equipment → Electronic parts catalogue.
–  Check for salt residue, dirt and leaves in air mass meter and air intake hose (engine intake side).
–  Check for dirt in air duct leading to air filter element. If contamination is found, remove salt residues, dirt and leaves from top and bottom part of air filter housing by rinsing out or using a vacuum cleaner if necessary.
–  Removing and installing air cleaner → Chapter.
Further installation is carried out in the reverse order.
